Most 'brine' is from out of statehttp://apocadocs.com/s.pl?1326673824
The industry uses the terms brine or produced waters to describe the salty waste fluid that constantly percolates out of wells drilled to tap oil and natural gas.
For decades, the best way for Ohio oil and gas companies to get rid of the stuff was to send it back underground. It's the sole purpose of a network of 177 disposal wells that state regulators have overseen since the 1980s.
State records show that nearly 60 percent of the brine that's injected into Ohio disposal wells these days doesn't come from Ohio. It's trucked in from shale gas wells drilled in Pennsylvania and West Virginia.
Though this flood of brine has been linked to a series of earthquakes in Youngstown, state regulators and industry officials say they have no ability to stop it.
